DOS prompt from GEOS on OG 100
------------------------------

IT IS POSSIBLE TO LAUNCH DOS AS A "SUB-PROCESS" ON OG 100!

When I have completed my version of OG TEXT MODE and having
received similar product (driver) from Marcus Groeber, I tried
DOS prompt the same way it can be evoked from GEOS on PC.

You need:

        1. OG TEXT MODE DRIVER
           (either OGTMODE.EXE by Marcus G., or my OGTEXT.COM)

        2. COMMAND.COM from OG drive A:

        3. Some aplications from GEOPUBLISH

                \privdata\launcher.geo
                \system\spool.geo
                \system\shell.geo
                \system\sysappl\manager.geo


Procedure (what I have done):

NOTE:   I am using INTERLNK from PC DOS to communicate with OG 100.
        This increases the transfer speed to some 115 Kbit/sec.

        
        1. Install the OG TEXT MODE DRIVER (please, read its instalation)
        2. copy OG command.com from A:\ on B:\
        3. change following line in CONFIG.SYS

                old:    Shell = a:\command.com /P
                new:    Shell = b:\command.com /P

        4. copy PC GEOS files into following directories on OG

                launcher.geo    b:\geoworks\privdata
                spool.geo       b:\geoworks\system
                shell.geo       b:\geoworks\system
                manager.geo     b:\geoworks\world

        5. RUN GEOS

           * new icon (GEO MANAGER) should appear
           * launch it
           * select menu:
        
                Utilities/Create Launcher

           * an OG file selector will appear
             - click onto the blank line to get to the b:\ where
               COMMAND.COM is placed
             - double click on the COMMAND.COM
        
           * another window will appear, too big to fit onto OG screen
             - press ENTER to continue (nothing to setup here)

           * you will return to GEOMANAGER
             - press "DOS" panel and you will see an icon with GEOS logo
               and COMMAND label

          DOUBLE CLICK THE ICON TO LAUNCH DOS FROM GEOS!

Ending remarks:

        -  Copy the COMMAND icon into WORLD directory to have in the HOME appl.
        -  I believe you can set other icons for other DOS appls.
        -  The DOS runs in BIG letter mode (INT 10/FN00) and the screen
           has inverted color from GEOS (if you have inverted color in GEOS
           DOS will be "normal")
        -  type "exit" to get back to GEOS



Enjoy it,
